Diagnostic Neuroimaging by Magnetic Resonance Imaging: Update

Magnetic resonance (MR) imaging remains the most versatile technique in diagnostic imaging. In addition to conventional imaging sequences such as T-1-weighted imaging, T-2-weighted imaging, or fluid-attenuated inversion recovery imaging, various techniques specific for certain pathological conditions are being continuously introduced. Pulse sequences for various imaging contrasts are becoming mature, and studies on high (3 T), or even ultra-high (7 T) field systems are emerging as a golden standard for neurosurgical practices. MR spectroscopic imaging capable of providing a pictorial display of the chemical properties of the brain and microscopic imaging providing images with significantly high anatomical resolution equivalent to histological preparations are now becoming essential for presurgical evaluation.
